If the mass of the electron (9xx10^(-31)kg) is taken as unit of mass, the radius of the first Bohr orbit (0.5xx10^(-10)m) as unit of length and 500 newton as the unit of force, then the unit of time in the new system would be

If the mass of the electron (9xx10^(-31)kg) is taken as unit of mass,

1.	If the mass of the electron (9xx10^(-31)kg) is taken as unit of mass, the radius of the first Bohr orbit (0.5xx10^(-10)m) as unit of length and 500 newton as the unit of force, then the unit of time in the new system would be
